Rheology control of nanocellulose treatment fluids
TL;DR: In this paper, the authors present methods and systems for controlling the rheology of a treatment fluid, which includes selecting a cellulose feedstock source and processing the cellulose with a processing technique to provide the nanocellulose with the average desired aspect ratio.
Journal ArticleDOI
Metal ion and ultrasonication assisted assembling chiral nematic coatings towards humidity-responsive and anti-counterfeiting
TL;DR: In this article , a facile and smart strategy for assembling humidity-responsive cellulose nanocrystal (CNC)/polyacrylic acid (PAA)-Na iridescent coatings, assisted by metal ion regulation and ultrasonication, is reported.

Structured Ultra‐Flyweight Aerogels by Interfacial Complexation: Self‐Assembly Enabling Multiscale Designs (Small 20/2022)
Milad Kamkar,Ahmadreza Ghaffarkhah,Rubina Ajdary,Yi Lu,Farhad Ahmadijokani,Sameer Mhatre,Elnaz Erfanian,Uttandaraman Sundararaj,Mohammad Arjmand,Orlando J. Rojas +9 more
TL;DR: In this article , Kamkar et al. devise types of biphasic soft materials featuring unique morphologies, e.g., continuous, multilayer, interpenetrated, and tubular structures, which allow for fabrication of structurally tunable and stable ultra-flyweight aerogels with unique worm-like morphologies.
